"Just because he has an apartment doesn't mean our work is done with him," Diamond says. "He is not dressed for the weather, he is not engaged in a healthy lifestyle, and he is not leading a productive life."

Hillman has been receiving Department of Homelessness services since 2009. From 2009-2011, Hillman lived in transitional housing sites called Safe Havens, and in 2011, he was judged stable enough to move into the regular private apartment.

"Housing is an important first step that builds the foundation, but there is more that needs to be done," Diamond says. "The initial problems that put them on the street need to be addressed like mental health, substance abuse, physical issues, employment."

Hillman does not always accept help.

"We continue to reach out to him, and we have had contact in the last few weeks," Diamond says. "Sometimes he appears to be receptive and other times less so. We never give up."

Since recognizing Hillman in the media, his high school class of 1976 from South Plainfield, N.J., has rallied for him.

More than 200 South Plainfield classmates gathered to organize the Jeffrey Hillman Survival Fund on Facebook.

"I'm very worried about him, considering that you realize he does have an apartment," says classmate Ellen Shapiro DeMaio. "The point is that he's lost. We have to somehow as a class -- since we're a family and he's still one of us -- be able to reach him and give him a helping hand up if we can. That's our main concern."

Hillman is back on the streets with no shoes.

A few days after the viral photo was posted, The New York Times found Hillman barefoot again and asked about the $100 all-weather boots. Hillman said he'd hidden them because "they are worth a lot of money."

He said he's grateful for the gift, but he wants "a piece of the pie" because the photo was posted online "without permission."
